Just wanted to pop in and share my experience as I see a lot of questions about it in a lot of posts.

Implantation spotting DOES NOT have to be brown or even light pink. I had a bit of pink exactly one week before AF was to arrive. next day it was red (not a ton but a pantyliner was necessary), next 2 days nothing, the follow day brown and red. Day AF was due got a BFP! I thought for sure AF was coming. Just goes to show it can vary from person to person.

I was SHOCKED with this pregnancy. I was sort of charting, but thought my O day was a lot earlier than I thought We were NOT TRYING, just had a moment of "not caring" I guess. We are excited though
